2 Claims. (Cl. 16-105) This invention relates to a hanger for sliding doors.

Either when initially installed or at a later time, vertical adjustment of a sliding door may be necessary to obtain proper fit or clearance at the bottom. In the first instance, variation in the installation of the rail on which said doors are hung and/ or variation in the height of the door may result in either too great a gap between the bottom edge of the door and the floor or guide rail therefor, or too tight a fit. In the case of doors already hung, the installation of carpeting therebeneath, or the like, may cause the doors to bind and operate improperly.

Accordingly, it is an object of this invention to provide an adjustable hanger whereby a sliding door may be hung from a track or rail in properly adjusted vertical position and later adjustment of said position made, as desired.

Another object of the invention is to provide a sliding door hanger that embodies slidingly adjustable members, one adapted to be aflixed to the door and the other mounting a track-engaging wheel and, after sliding adjustment as desired, may be locked or secured to the first member to retain the adjustment.

The invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novel combinations and arrangements of parts,

' which will more fully appear in the course of the following description. However, the drawing merely shows and the following description merely describes, preferred embodiments of the present invention, which are given by way of illustration or example only.

In the drawing, like reference characters designate similar parts in the several views.

Fig. 1 is a vertical sectional view taken through the framing of a sliding door and showing one form of door hanger according to the invention.

Fig. 2 is a cross-sectional view as taken on line 2-2 of Fig. 1, with parts broken away.

Fig. 3 is a front elevational view of another form of hanger according to the invention.

Fig. 4 is an edge view thereof.

Figs. 5 and 6 are views respectively similar to Figs. 3 and 4 of still another form of hanger according to the invention.

With particular reference to Figs. 1 and 2, a track of rail 10 is horizontally disposed within a bottom-open enclosure 11 that, in the usual manner, is framed into a partition, ceiling, or other portion of a building structure. A sliding door 12 is disposed beneath said closure, substantially as shown, to close or open a space, as the case may be, between stiles 13 at one end of enclosure 11 and similar stiles at the other end. The above is generally conventional and is varied in many ways, but sets forth one environment in which a hanger 14, according to the present invention, is adapted to be used. While one such hanger is shown, in practice two or more are used in suitably spaced relation.

The present hanger 14 comprises, generally, a bracket 15 adapted to be aifixed to door 12, an adjustable member 16 engaged with said bracket and mounting a roller or wheel 17, and means 18 to lock the adjustment of the member relative to the bracket so as to locate the wheel 17 in suitably elevated relation to the top edge of door 12. With the wheel 17 engaged in track 10, it will be clear that the more elevated the wheel is relative to the door top, the lower will the door hang.

In the form of Figs. 1 and 2, the bracket 15 comprises an angle member having one leg 19 aflixed to the top edge of door 12 and the other leg 20 vertically disposed and provided with a tapped hole 21 intermediate its height.

The adjustable member 16 is shown as a strap 22, on one end of which wheel 17 is revolubly carried, the other end being provided with a sloping slot 23.

The means 18 comprises a screw 24 that passes through slot 23 and is entered in tapped hole 21; the head of said screw may be tightened against the strap 22 or, as shown, against a washer 25.

The limit of adjustability is determined by the degree of slope of slot 23. Therefore, by sliding the strap along the face of angle leg 20 to adjust the position of wheel 17 and then tightening the means 18, the hanger elements are locked together and the door 12 will hang according to the adjustment made. Offset lugs 20a engage and guide the sliding movement of strap 22.

In the form of Figs. 3 and 4, the bracket 15 is similar to the one described, except that the tapped hole is omitted. Instead, a pivot pin or rivet 26 slidingly and pivotaily mounts a plate 27 in lieu of strap 22, although said plate may be formed as a strap, if desired. The wheel 17 is as before described.

In this form, the adjustment is made by means of a screw 24, similar to the one described, and an arcuate slot 28 in angle leg 20 and generated on pin 26 as a center. In this case, said screw is entered through slot 28 and the tapped hole 29 therefor is provided in plate 27.

The hanger thus provided can be adjusted between the low-hanging position of the door, as shown in full lines, and any other position as limited by slot 28 and as suggested by the dot-dash lines. In this connection, it is noted that the tapped hole of Figs. 1 and 2 may be provided in the strap 22 and the slot in angle leg 20 in the manner in which the comparable parts are provided in the form of Figs. 3 and 4.

In the form of Figs. 5 and 6, the bracket 15 has the pivot pin 26 adjacent one end rather than in the center, as in Fig. 3, and the slot 30 is straight and horizontal instead of arcuate, as before. A strap arm 31 is pivotally mounted, by one end, on pin 26 and carries wheel 17 at the other end.

Arm 31 is adjusted between the full line position shown to a lower position, as represented by the dot-dash lines, by means of a link 32 connected at one end to an intermediate portion of arm 31 by a pivot pin 33 and at the other to bracket 15 by the screw 24 of lock means 18. Thus, arm 31 is angularly adjustable relative to bracket 15 to adjust the wheel 17, as desired.

While the foregoing has illustrated and described what is now contemplated to be the best modes of carrying out the invention, the constructions are, of course, subject to modification without departing from the spirit and scope of the invention. It is, therefore, not desired to restrict the invention to the particular forms of construction illustrated and described, but to cover all modifications that may fall within the scope of the appended claims.

Having thus described the invention, what is claimed and desired to be secured by Letters Patent is:

l. A sliding door hanger comprising a bracket member adapted to be affixed to a sliding door, an adjustable member adjustably connected to said bracket member, one of said members having a slot therein and the other member having a hole therein, locking means extending through said slot and said hole for adjustably connecting the bracket member and the adjustable member, a wheel rotatably mounted on said adjustable member, said wheel and said locking means being located on opposite ends of said adjustable member, and a pivot interconnecting said bracket member and said adjustable member, said pivot being located on a line extending between the centers of said wheel and said locking means.

2. A sliding door hanger comprising a bracket member adapted to be afiixed to a sliding door, an adjustable member adjustably connected to said bracket member, one of said members having an arcuate slot therein, a wheel rotatably mounted at one end of said adjustable member, a pivot interconnecting said bracket member and said adjustable member, and locking means extending through said slot for locking said adjustable member in position on said bracket member, said locking means being located at the other end of said adjustable member, said pivot being intermediate the wheel and the locking means.
